Abstract: In order, for the levelling of a sheet-like material, not to have to rely on the use of a tentering frame involving a high outlay and taking up a relatively large amount of space, a device with transport elements (5) grasping the sheet-like material (7) along its two edge strips in the tentered state is proposed, these transport elements being arranged distributed on the outer circumference of wheels (2). The planes of the wheels (2) are adjustable relative to one another both at differing parallel spacings and differing angles. <IMAGE>

Abstract: Method and system for processing a change value within a system having a number of components operating as participants, a first component having an arithmetic section, which from outside is at least partially unreachable and which has a register which is unreachable directly from outside, and a second component supplying a message, which comprises a change value, to the first component for the purpose of changing the contents of the register. The first component contains a set of elements, which represent numbers which are divided into rows, each second and subsequent element of each row being determined, by application of one or more one-way functions, from the directly preceding element of the row. The second component receives a first datum which is a function of numbers underlying the set or of the last elements thereof. In response to receiving the message originating from the second component, the first component has to send elements from a number of rows to the second component. The second component evaluates the last-mentioned received elements on the basis of the indices sent and by application of the one-way functions to the last elements of the rows in question, and therefrom obtains a second datum. If the first and second data, which may first have been elaborated further, are identical, the second component judges the register contents to have been changed correctly.

Filed: 1992-11-12
Abstract: The invention relates to a method of establishing and maintaining in sealed tents or the like mobile units, an environment which is independent of the surroundings with regard to temperature and contamination. The invention is characterized by taking air from the surroundings, extracting contaminated particles and gas from the air by filtration, and causing the air to pass into the mobile unit so as to establish a predetermined air pressure which is higher than the air pressure of the surroundings. The filtered air is mixed with air recycled from within the mobile unit when the aforesaid predetermined air pressure has been reached and mixing of the filtered air with recycled air is continued for as long as the internal air pressure is equal to or greater than the predetermined air pressure. The air mixture is heated or cooled to a predetermined temperature and is then distributed essentially uniformly in the mobile unit and filtered, in conjunction therewith, so as to extract any remaining particles and gas. 
     The invention also relates to an arrangement for carrying out the method.

Title: Distillation apparatus.
Inventor: KOISTINEN PETER
IPC: C02F1/04
Filed: 1991-12-16
Abstract: The invention relates to a distillation apparatus (1) which is suitable in particular for the distillation of sea water into fresh water. The apparatus comprises a plurality of flat, bag-like elements (3) formed from a thin film material such as plastic film and placed one against the other, the elements serving as heat exchangers between a vaporizing liquid flowing along the exterior surfaces of the element and a condensing vapor directed to the inside of the element, and a compressor (15) for increasing the pressure and temperature of the generated vapor before it is directed to the inside of the elements. The essential idea of the invention is that at the upper end of each bag-like element (3) there is a honeycomb-structured end strip (4) having substantially the width of the element, the strip containing parallel feeding ducts (26) separated from each other by partition walls, the ducts distributing the liquid to be evaporated over the entire width of the element surface. In addition, the strip (4) may contain ducts (25), formed in the same manner, which direct the vapor to be condensed to the inside of the element over the entire width of its end. At the lower end of the element there may additionally be a honeycomb-structured end strip (7), the ducts contained therein collecting the produced distillate into a collection vessel (8) and discharging any unvaporized liquid into a collection basin (9).

Abstract: Die Erfindung betrifft eine Klopfregelung einer fremdgezündeten Brennkraftmaschine mit einer Kurzzeitregelung, bei der beim Auftreten von Klopfereignissen der Wert für einen aktuellen Zündzeitpunkt ausgehend von einer Kennfeldvorgabe (αV) in Richtung Spätzündung zurückgenommen wird (SK). Beim Ausbleiben von Klopfereignissen wird der aktuelle Zündzeitpunkt in Richtung Frühzündung wieder auf die Kennfeldvorgabe hingeführt (FK). Erfindungsgemäß ist eine Langzeit-Anpassung dergestalt vorgesehen, daß die Kennfeldvorgabe (αV) bei auftretenden Klopfereignissen (K) um einen Anpassungswert (LZW bzw. LZK) von der Klopfgrenze weg zurückgenommen bzw. modifiziert  wird, so daß die Kurzzeitregelung auf eine neue Zündzeitpunktvorgabe bzw. ein anderes Niveau (αLZW bzw. αLZK) bezogen ist. Anpassungswerte (LZW) werden nur bei betriebswarmer Brennkraftmaschine bzw. über einem bestimmten Temperaturschwellwert (TS) ermittelt oder geändert. Unterhalb des Temperaturschwellwerts (TS) werden die Anpassungwerte (LZW) bevorzugt temperaturabhängig bewertet und reduziert, wodurch die Klopfregelung einer geringeren Klopfneigung der Brennkraftmaschine nach einem Kaltstart angepaßt wird.

Title: Electrostatic roller transfer of toned images from a photoconductor member to a sheet substrate.
Inventor: BHAGAT GOPAL C
IPC: G03G15/16
Filed: 1992-01-30
Abstract: An electrically biased attracter roller is utilized in an electrophotographic image reproduction machine, in place of a conventional corotron device, to electrically transfer toner from the side of a rotating photoconductor drum onto a side surface of paper stock being operatively fed through the machine. The charged roller is spring-biased into forcible side-to-side engagement with the drum and is frictionally rotated by the drum. The paper stock is fed between the rotating roller and drum and, by a combination of pressure and electrical attractive force, the roller very efficiently transfers toner from the drum to the paper. To further improve the overall effectiveness of the attracter roller, a humidity compensation system is provided and is operative to automatically adjust the bias voltage of the roller, and thus the electrical toner attraction force thereof, in response to sensed humidity variations within the machine housing.
